We describe the urological complications occurred in 237 patients undergoing cadaveric renal transplant in 13 years.

Two techniques of extravesical ureterocystoneostomy were used. Thirty patients (13%) presented 35 (15%) urological complications: 23 (9.7%) urinary fistula and 12 (5.1%) ureteral stenosis. The vast majority (80%) were early complications (before 90 days): 82% fistulas and 18% stenosis. All early complications were identified as technical deficiencies; all late complications were obstructive in nature. A new ureteral reimplant was performed in 15 patients, with successful results in 14.

Six patients underwent nephrectomy and pyelostomy, 2 of these required a second operation. Seven patients underwent endo-urological procedures with good results.

Three patients undergoing conservative treatment for urinary fistula required surgical drainage of an infected urinoma. No statistical difference was observed in the survival rates of both the grafts and the patients presenting or not urinary complications.
